NIVELCO PJK-100 User Manual

We are sure that you will be satisfied throughout its use!
1. APPLICATION
The UNICONT PJK-1 -4 is a universal interface module that
can be controlled via HART or MODBUS protocol through an RS485
interface, and (depending on type) provides relay(s) and/or 4...20 mA
current output(s).
The device is intelligent, the internal functions and services can be
set with the help of a communication protocol: the transmitter outputs
can be scaled. The error detection function can be switched on and
off. The state, in which a given output unit should be when an error
occurs, can also be set. The device can be used with Nivelco's
MultiCONT PR -1 - units as an output extension module,
and also as a peripheral device for PLC or PC controlled process
control systems.

OMMUNICATION TERMINALS
Wiring example when using a MultiCONT:
Connection with shielded twisted pair cable, shielding is
grounded at one point on the MultiCONT side.
The terminal resistor is connected to the two farthest points
of the cable. (TB and B contacts are connected in PJK 100;
and on the MultiCONT the K2 terminal resistor, located
next to the terminals, is switched on.)

5.1.2 S ETTING THE DEVICE ADDRESS
A communication line can contain max. 32
Universal Interface Modules. These modules
should have different addresses.
Set the address with the „ADDRESS" DIP

Description of the Communication
Protocol
The Universal Interface Modules should be
connected one after another to one cable
pair. Star topology is not allowed. Max. cable
length is 1000 m, but in this case a shielded
twisted cable pair (STP – Shielded Twisted
Pair) should be used. Max. cable capacity
should be less than 100 pF/m.
All of the Universal Interface Modules in one
system should have different addresses
(0...31), see: 5.1.2.
